SIMD and multithreading support really helped with closing the performance gap.

Still surprised about the 5% though- I’ve generally seen quite a bit more of a gap.

Maybe the emulator code is particularly WASM friendly ... it's mostly bit twiddling on 64-bit integers with very little regular integer math (except incrementing counters) and relatively few memory load/stores.
